A reply is\nsent (again a JSON formatted string) of the current DPDK metrics.\n\nThe telemetry component makes use of the existing rte_metrics library to\nquery values. The values to be transmitted via the telemetry infrastructure\nmust be present in the Metrics library. Currently the ethdev values are\npushed to the metrics library, and the queried from there – there is an\nopen question on how applications would like this to occur. Currently only\nethdev to metrics functionality is implemented, however other subsystems\nlike crypto, eventdev, keepalive etc can use similar mechanisms.\n\nExposing DPDK Telemetry via a socket interface enables service assurance\nagents like collectd to consume data from DPDK. This is vital for\nmonitoring, fault-detection, and error reporting. A collectd plugin has\nbeen created to interact with the DPDK Telemetry component, showing how it\ncan be used in practice. The collectd plugin patch can be found at\nlib/librte_telemetry/collectd_plugin/v1-0001-dpdk_telemetry-add-plugin-\nfor-DPDK-metrics-via-DP.patch, this will be upstreamed to collectd at a\nlater stage. Further instructions on applying the collectd patch can be\nfound in the collectd patch commit message. A small python script is\nprovided in ./usertools/telemetry_client.py to quick-start using\nDPDK Telemetry.\n\nCiara Power and Brian Archbold (10):\n telemetry: initial telemetry infrastructure\n telemetry: add initial connection socket\n telemetry: add client feature and sockets\n telemetry: add parser for client socket messages\n telemetry: update metrics before sending stats\n telemetry: format json response when sending stats\n telemetry: add tests for telemetry api\n telemetry: add vdev kvargs for selftest\n doc: add telemetry documentation\n usertools: add client python script for telemetry\n\nEmma Kenny (1) :\n telemetry: add collectd plugin patch\n\n config/common_base | 5 +\n doc/guides/howto/index.rst | 1 +\n doc/guides/howto/telemetry.rst | 86 +\n drivers/Makefile | 3 +\n drivers/meson.build | 3 +-\n drivers/telemetry/Makefile | 8 +\n drivers/telemetry/meson.build | 6 +\n drivers/telemetry/telemetry/Makefile | 26 +\n drivers/telemetry/telemetry/meson.build | 5 +\n .../telemetry/rte_pmd_telemetry_version.map | 9 +\n drivers/telemetry/telemetry/telemetry_driver.c | 83 +\n lib/Makefile | 2 +\n lib/librte_telemetry/Makefile | 28 +\n ...emetry-add-plugin-for-DPDK-metrics-via-DP.patch | 578 +++++++\n lib/librte_telemetry/meson.build | 9 +\n lib/librte_telemetry/rte_telemetry.c | 1737 ++++++++++++++++++++\n lib/librte_telemetry/rte_telemetry.h | 58 +\n lib/librte_telemetry/rte_telemetry_internal.h | 72 +\n lib/librte_telemetry/rte_telemetry_parser.c | 604 +++++++\n lib/librte_telemetry/rte_telemetry_parser.h | 13 +\n lib/librte_telemetry/rte_telemetry_parser_test.c | 574 +++++++\n lib/librte_telemetry/rte_telemetry_parser_test.h | 39 +\n lib/librte_telemetry/rte_telemetry_socket_tests.h | 36 +\n lib/librte_telemetry/rte_telemetry_version.map | 7 +\n lib/meson.build | 2 +-\n mk/rte.app.mk | 2 +\n usertools/telemetry_client.py | 116 ++\n 27 files changed, 4110 insertions(+), 2 deletions(-)\n create mode 100644 doc/guides/howto/telemetry.rst\n create mode 100644 drivers/telemetry/Makefile\n create mode 100644 drivers/telemetry/meson.build\n create mode 100644 drivers/telemetry/telemetry/Makefile\n create mode 100644 drivers/telemetry/telemetry/meson.build\n create mode 100644 drivers/telemetry/telemetry/rte_pmd_telemetry_version.map\n create mode 100644 drivers/telemetry/telemetry/telemetry_driver.c\n create mode 100644 lib/librte_telemetry/Makefile\n create mode 100644 lib/librte_telemetry/collectd_plugin/v1-0001-dpdk_telemetry-add-plugin-for-DPDK-metrics-via-DP.patch\n create mode 100644 lib/librte_telemetry/meson.build\n create mode 100644 lib/librte_telemetry/rte_telemetry.c\n create mode 100644 lib/librte_telemetry/rte_telemetry.h\n create mode 100644 lib/librte_telemetry/rte_telemetry_internal.h\n create mode 100644 lib/librte_telemetry/rte_telemetry_parser.c\n create mode 100644 lib/librte_telemetry/rte_telemetry_parser.h\n create mode 100644 lib/librte_telemetry/rte_telemetry_parser_test.c\n create mode 100644 lib/librte_telemetry/rte_telemetry_parser_test.h\n create mode 100644 lib/librte_telemetry/rte_telemetry_socket_tests.h\n create mode 100644 lib/librte_telemetry/rte_telemetry_version.map\n create mode 100644 usertools/telemetry_client.py" }
